Highlight <pre> in HTML block

[sbliven]

I sometimes prefer including code as a <pre> element within an HTML block rather than as a separate code block (for instance when embedding code in lists). Is there any way to trigger syntax highlighting in HTML blocks?

It's possible. It would basically involve the same approach as extending for use in comments: #24 (comment).

@westonruter should we add common functionality like this to the Wiki? Like have a section of filters that people can use on their websites?

[westonruter]

Yeah. I wonder though if we should make it a bit easier than what is currently involved in https://gist.github.com/westonruter/d35a909df087d90e0100d111eed77faa

Instead of calling our render_block() function, perhaps there should be a render() function that does most of what that filter_comment_text() function does.
